Bitcoin slid another 13 per cent to below $6,000 on Tuesday, bringing the world's best-known cryptocurrency's losses to more than half since the start of 2018.
Bitcoin has fallen heavily in recent sessions as worries about a regulatory clampdown on the nascent market and panicked investors push prices lower. The virtual currency hit a peak of almost $20,000 in December.
On the Luxembourg-based bitstamp exchange, bitcoin fell to as low as $5,920, its lowest level since mid-November, before recovering slightly. Other cryptocurrencies have also dropped sharply in value this week.
